Tomorrow’s aircraft could contribute to their power needs by harnessing energy from the wheel rotation of their landing gear to generate electricity.
They could use this to power their taxiing to and from airport buildings, reducing the need to use their jet engines. This would save on aviation fuel, cut emissions and reduce noise pollution at airports.
Next-generation drones may fly like Luke Skywalker zipping through the Endor forest on a speeder bike, suggests new research which focuses on how birds such as northern goshawks determine their maximum speed limit.
These birds race after prey through the forest canopy without smacking into tree trunks.
They avoid this fate by observing a theoretical speed limit, according to scientists at the Massachusetts Institute of Technology.
